I think Sonic 1 HD Sonic should look alot like generations but cartoony. (Can't see his mouth when he's standing.)
Sonic 2 HD should look much like the Alpha except without those shadows that would make Mystic Cave and Hill Top Zone awkward... (Smiling when standing)
Sonic 3 HD should be some hybrid between cartoony and 3D Graphics. (indifferent when standing.) Even the badniks in the manual are 3D and aren't concept art anymore.
Sonic 4 SHOULD have been like a full 3D Classic Sonic with green eyes, soles on his shoes, and physics and level design based off of and improved from Sonic 3 and Knuckles. They had the right idea making Metal Sonic Playable though.
When sonic hits a speed shoe box, I think his shoes should glow light orange and red, like Super Sonic glows yellow and white. Also, his waiting animation should go from him with his hands on his hips tapping his foot, to him crossing his arms and tapping his foot like 10 times a second.
All of these projects could use an extra 3D Option kind of like CHEESE QUEST 3D off of Foster's home for imaginary friends. All you'd have to do is show the sprites' red and cyan versions next to each other based on the depth. Maybe you could also do this by separating a sprite's RGB values. The hardest part would be making some of the background parts 3D. Make it so the HUD gets no 3D affect. Generations did this and it's like your looking at the game through glass and it makes it even more awesome somehow. When you hit the boss, make the HUD flash.
One thing about S2HD is it din't feel as fast. This is because the screen size is different. Instead of 2 screens a second, he runs about 1 screen a second. You could have an option to keep the window the same relative size/fill in the extra space with black, but you could also have an option where Sonic's top speed and acceleration are doubled!
I don't know if you're planning to make your own S2HD, but I'd want to see the beginning look similar to the game starting. Instead of the black screen with "produced by or under licence from sega enterprises ltd", it could be the disclaimer page. Then it could say Team S3HD if that's your name. Then have the Sonic retro theme play, have a pixely sonic run to the left, showing most of "SONIC RETRO" and a grey master emerald, have sonic run to the right, brake, then jump on the emerald, and make the screen flash so the master emerald turns green, Sonic is in HD now, the Japanese characters appear, and the music starts playing in HD. Then have a black screen that says Sonic and Miles "Tails" Prower in 4x Definition.
Something a little different about Sonic 3 and Knuckles is it has 2 different types of music. There's the original genesis, but then when it was ported to the computer, most of the music was drastically changed. You might want an option to switch between the two music types or even have a hybrid of the two.
I think it would be epic in Sonic 1 HD if when you get a continue, it looks like the original regular waiting animation. It might be hard to do that in Sonic 3 HD. Might have to make a new graphic. I think this affect would work extremely well at the end when the tornado saves sonic, then they fly behind Angel Island. Just change it so it still says SONIC when it's facing the opposite way.
Maybe you could add a hard mode where all the spikes are like Sonic 1, the level design is different, Sonic drops a MAX of 16 rings instead of 32, Tails looses 10 or 5 rings every time he's hit, but hidden red star rings give you 10,000 points. Find 5 and the points will give you an extra life. It's not likely, but if Sonic 1-3 HD are released, it would be cool to play through the entire set with whatever character you want. Getting the emeralds would give you ablities. Sonic1=spin dash Sonic2=insta shield Sonic3=super sonic Sonic&Knuckles=hyper sonic SonicCD=ramming into spikes destroys them Since Knuckles already has the glide, maybe it could be replaced with keeping his rings from before a special stage or something...
It would be awesome if all the HD games had that thing in S3&K where when you hold C and press B, the character cycles through all his animations. It would also be nice if you had an option to take a picture with F9 and have the same save a full resolution PNG to a screenshot folder. Make it so you can edit the controls from outside of the game. S2HD got a bad rap for Direct Input, but maybe it's not all bad. Have DI be the default for a controller, but have RAW32 be the default for the keyboard.
Seems like the playable character list from most to least importance is Sonic, Tails, Knuckles, Metal Sonic, and Emerl. :P Ya gotta admit, Metal rocks and Emerl doesn't get enough love.
Some of these ideas are way out there, but sometimes ya gotta think ahead. I don't want this project to crash and burn like S2HD, but I want it to be something worth doing like S2HD. It's a project for the fans, by the fans, of the highest quality possible. I'd want this to be the definitive, no doubt, best version of this game. Make all those graphics (except turning around) smooth. Good luck with your project.
